Libraries in debug mode ?

[SteM]

Hi all,
is there a way to have the QT libraries in 'debug version' to allow the developed to trace step-by-step into the QT calls?
Do i need a version with the symbols included?
How can i buils them?

Thanks !!

In short, see "configure -help".

PS. On Windows there is a shortcut for building debug libs in the start menu (provided that Qt was installed from a binary installer).

Thanks a lot.
What about to compile an application in debug mode, with its symbols?

Can i debug them with the 'standard' gdb or do i need some other tools?

Thansk again !

Yes, gdb is fine. Either invoke:

qmake -config debug

or add

CONFIG += debug

to the .pro file and rebuild the application.

Thanks again!
In the project i received I read the .pro file and i see the debug option set, but it reports it is generated automatically by qmake.
How can i generate it for debug and release version?

PS: I typed 'qmake -help' and i didn't see -config option

Thanks again !!

If you want to build both debug and release: Building in Both Modes. I couldn't spot documentation for "qmake -config" but it's being used for example all over the examples. There are a few undocumented features in qmake.
